STAY-ROLLER FOR SLIDING DOORS.

SPECIFICATION forming part of Letters Patent No. 308,177, dated November18, 1884.

Application filed Jun To aZZ whom it may concern.-

Be it known that I, EMIL LAASS, of Syracuse, in the county of Onondaga,in the State of New York, have invented new and useful Improvements inStays for Suspended Sliding Doors, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to the class of doorstays employed for guidingthe bottom portion of a suspended sliding door.

The object of the invention is to provide a door-stay which shall beadjustable so as to adapt it for use in connection with doors ofdifferent thicknesses without changing the position of the guide-rolleron its sustaining-arm, thus obtaining a more secure support for saidroller.

The invention consists, essentially, in the combination of anattaching-plate, an arm device forretaining the arm in its position, anda bearing on the free end of the arm engaging the door, all ashereinafter more fully described and set forth in the claims.

In the annexed drawings, Figure I is an edge view of the bottom portionof a suspended sliding door guided by my improved door-stay. Fig. II isa front view of my i11- vention. Fig. III isa plan View of the same.Fig. IV is a plan view of a modification of the construction of theattachingplate. Fig. V is a side view of the stay-arm to be used inconnection with said attaching-plate, and Fig. VI illustrates amodification of my invention. D denotes thebottom portion of a suspendedsliding door.

B represents the attaching-plate of the doorstay, said plate beingrigidly secured in any suitable and Well-known manner to the side of thebuilding beneath the bottom edge of the door.

A is an arm pivoted or hinged on the plate B in such a manner as toallow the free end of said arm to be swung laterally. The plate B isprovided with a serrated, corrugated, or notched surface, a, which maybe either on top or on the edge of a projection, 12, on said plate,

j ection b, as illustrated in Fig. IV of the draw by correspondingserrations or corrugations on said arm engaging with those of theprojection b or eye 6, as shown respectively in Figs. I, II, III, and IVof the drawings, or by a pin, 8, which may be either integral with thearm A or inserted removably in an aperture in said arm, and engages withone of the series of notches in the edge of the projection 12, as shownin Fig. VI of the drawings. By means of either a key or nut on the endof the gudgeon d, the arm A is clamped on the attaching-plate. The freeend of the arm A is provided with a pivot, f, for the roller R, whichbears on the door to guide and steady the same in its movement. Thepivotal pin f may be either made integral with the arm A and the rollerjournaled on said pin, or the pin may be affixed to the roller andpivoted on the arm. In either case the said pin is maintained in oneposition and always at a uniform distance from the attaching end of thearm during theadjustment of said arm required to bring the roller tobear on doors of different thicknesses. Vhen it becomes necessary toadjust the arm A, as aforesaid, the clamping device which fastens thearm on the attaching-plate is to be loosened or removed. and either thearm is to be raised to liberate the serrated or corrugated bearings orthe pin 8 is to be withdrawn from the notch a in the projection 22,(shown in Fig. VI of the drawings,) then after swinging the arm Alaterally until the roller B touches the door, the arm 0 is to be againclamped on the attachingplate, and is thus retained in its requiredposition.

It is obvious that an angular or polygonal gudgeon, d, on the arm Aentering a corre spondingly-shaped eye, 6, in the attachingplate, willanswer the purpose of the hereinbefore-described devices for locking thearm A in its position; hence I do not limit myself to any specific formof said locking device.

that I- claim as my invention isas shown respectively in Figs. I, II,III, and VI of the drawings, or in the eye 6 in the pro- 1.- As a newarticle of manufacture, an adj ustable stay for suspended sliding doors,conretain said arm in its required position, either In testimony whereofIhave hereunto signed my name and affixed my seal, in the presence oftwo attesting witnesses, at Syracuse, in the I 5 county of Onondaga, inthe State of New York, 1 this 6th day of June, 1884,

EMIL LAASS. [L. s]
